I have this problem,i add the following 3 JPanels to the JTabbedPane but when i display the JTabbedPane in the GUI,the first tab is selected by default at the start,The 3 tabs overlap for some reason(you can see all the data form the 3 tabs behind the tab in front),If i select all the tabs then they go back to normal,is there anyway you know know to fix this.
public void cretateJTabbedPane()
           JPanel theTabbedPanel = new JPanel();
           tabbedPane = new JTabbedPane(JTabbedPane.BOTTOM);
           tabbedPane.setSize(400,700);
           tabbedPane.addTab("Main Options", mainHeadingSection);
           tabbedPane.addTab("Options ", otherOptionsSection);
           tabbedPane.addTab(" Product Version ", prodVersionSection);
           theTabbedPanel.add(tabbedPane);
          theTabbedPanel.setMinimumSize(new Dimension(400,700));
          theTabbedPanel.setPreferredSize(new Dimension(400,700));
     addComp(theTabbedPanel,this,gb1,gbc,0,1,1,1,1,1,gbc.NORTH);
     addComp(buttonSection,this,gb1,gbc,0,0,1,1,1,1,gbc.NORTH);
     tabbedPane.setSelectedIndex(0);
}

Answer 1

As stated in my comment, dragging the empty icons out of the toolbar and trashing them, then accessing the Toolbar customizing function, everything was returned to normal.
